While AI improves threat detection, it also introduces risks as attackers can use it to develop advanced attack methods. Organizations must balance these risks. Reference: [CCSK Study Guide, Domain 12 - AI and Security]

Including key metrics and periodic reassessment in cybersecurity governance is essential for ensuring the effective and continuous improvement of security measures. Metrics provide a way to assess the current state of security, identify gaps, and measure progress over time. Periodic reassessment allows organizations to adapt to emerging threats and vulnerabilities, ensuring that security controls remain relevant and effective as the threat landscape evolves.

While meeting legal requirements is important, the primary reason for metrics and reassessment is continuous improvement, not just legal compliance. Documenting cybersecurity incidents is important, but the main focus of key metrics and reassessment is improving and adapting security strategies. Zero security incidents is not feasible; the goal is to reduce incidents and manage risk, not to eliminate all incidents entirely.

The correct answer isB. Customers retain control over their encryption keys.

Usingcustomer-managed encryption keys (CMEK)with a cloudKey Management Service (KMS)allows the customer toretain full control over the encryption keysused to encrypt their data. This is crucial in maintaining data sovereignty, privacy, and compliance with regulatory requirements.

Key Benefits of Customer-Managed Encryption Keys:

Key Ownership and Control:Unlike cloud provider-managed keys, CMEK ensures that the customer has full authority over the key's lifecycle, including creation, rotation, and deletion.

Enhanced Security:Customers can enforce strict access controls and audit who accesses the keys.

Compliance:Many regulations (like GDPR or HIPAA) mandate that data owners maintain control over encryption keys.

Data Privacy:Even though the data is stored on the cloud, the provider cannot access unencrypted data without the customer's permission.

Flexibility:Customers can choose when to revoke or rotate keys, which directly impacts data availability and access.

Why Other Options Are Incorrect:

A. Bypass the need for encryption:CMEK does not eliminate the need for encryption; it strengthens it by giving customers direct control.

C. Share encryption keys more easily:Sharing encryption keys can increase security risks, and CMEK is designed to restrict, not ease, key sharing.

D. Reduces computational load on the cloud service provider:CMEK does not impact the computational load. It focuses on key management and control rather than reducing processing overhead.

Real-World Example:

InAWS KMS, using CMEK allows customers to bring their own keys (BYOK) and manage them directly through AWS Key Management Service. Similar practices exist inGoogle Cloud KMSandAzure Key Vault, where customers can generate and control their own encryption keys.

Practical Use Case:

A healthcare provider using a cloud service to store patient records may use CMEK to ensure that sensitive data is encrypted under keys they control, ensuring compliance with regulations likeHIPAA.

Agile security approaches allow organizations to adapt to the rapid changes and emerging threats characteristic of cloud environments. Reference: [Security Guidance v5, Domain 4 - Organization Management]

During the Detection and Analysis phase of incident response, the primary objective is to validate alerts to determine whether they represent a genuine security incident, and to estimate the scope of the incident to understand the potential impact on the organization. This phase involves analyzing evidence, confirming the nature of the incident, and gathering the necessary information to move forward with containment and remediation.

Developing and updating incident response policies is important but occurs more during the preparation phase, not during the detection and analysis of an active incident. Performing detailed forensic investigations typically takes place during later phases, such as Containment, Eradication, & Recovery or Post-Incident Analysis. Implementing network segmentation and isolation may be part of the Containment phase but is not the primary focus during the Detection and Analysis phase.

In a cloud computing incident, the initial focus of analysis should be on the management plane activity logs due to the ephemeral nature of resources and centralized control mechanisms in cloud environments. The management plane controls and monitors the overall cloud infrastructure, and its activity logs provide crucial information about changes to configurations, access controls, resource provisioning, and administrative actions that can help identify the root cause of an incident.

Network perimeter monitoring and endpoint protection status are also important, but in cloud environments where resources can be rapidly provisioned and decommissioned, the management plane logs provide the most immediate insight into administrative actions and the overall state of the cloud environment.

Physical hardware access is generally the responsibility of the cloud provider and less relevant in the initial stages of a cloud incident analysis, especially when focusing on virtualized and managed resources.
